Add AMD work around in Vulkan to create a new secondary command buffer
whenever we change the VkPipeline. All these secondary CBs are still
submitted within one render pass.

This works around the amd bug linked in the bug below. It will probably
cause a slight performance hit, so I will track it on perf and revert if
the hit is significant.
